This is a fantastic new addition to our lineup and one that we worked hard with our factory to get right. This is not a twinkle strand with a subtle on/off - this is a true *pop* strobe 5mm strand that creates a fantastic effect in your light display. This version has 3 static pure white bulbs between each strobing LED - we designed them specifically for use in tree and shrub wrapping in static displays that want to add some really elegant sparkle. Every 4th bulb on this strand strobes randomly to create the effect of tiny camera flashes. When wrapped around a tree, through shrubs or on any structure, this strand will make your display sparkle. When used with computer controlled displays, these are non-dimmable. For a static display, these can be left on all night to create a magical environment. View the demo video here:
